In case you've not got anywhere with this, I replicated your code in
VB.NET and it worked:
---- AppDomTest.vb ----
Option Explicit On
Option Strict On
Module ADTest
Sub Main()
Dim ap_setup As New System.AppDomainSetup()
ap_setup.LoaderOptimization = System.LoaderOptimization.MultiDomain
Dim ap As AppDomain = AppDomain.CreateDomain("DomainForWork", Nothing, ap_setup)
Dim pe As New System.Security.Policy.Evidence()
pe.AddAssembly(ap)
Dim a As System.Reflection.Assembly = ap.Load("Classes", pe)
Dim t As System.Type = a.GetType("Global")
Dim mi As System.Reflection.MethodInfo = t.GetMethod("InitColl")
mi.Invoke(Nothing, Nothing)
Dim ap_setup2 As New System.AppDomainSetup()
ap_setup2.LoaderOptimization = System.LoaderOptimization.MultiDomain
Dim ap2 As AppDomain = AppDomain.CreateDomain("DomainForWork2",
Nothing, ap_setup2)
Dim pe2 As New System.Security.Policy.Evidence()
pe2.AddAssembly(ap2)
Dim a2 As System.Reflection.Assembly = ap2.Load("Classes", pe2)
Dim t2 As System.Type = a2.GetType("Global")
Dim mi2 As System.Reflection.MethodInfo = t2.GetMethod("InitColl")
mi2.Invoke(Nothing, Nothing)
End Sub
End Module
--- Ends ---
--- Classes.vb ---
' Compiled to Classes.dll
Option Explicit On
Option Strict On
Module Global
Sub InitColl()
MsgBox("InitColl called")
End Sub
End Module
--- Ends ---
So it's probably somthing else. Can InitColl throw the exception you're getting?
